1 Claim. (Cl. Ztl- 69) This invention relates to draft seals, isparticularly concerned with draft seals for doors, and is moreparticularly concerned with seals adapted for silencing.

In the prior art there are door seals of many different descriptions andof many different structures. Most of these door seals are made of verythin metal sheets, usually made of copper or brass, and are eithertubular in structure or are in the shape of substantial crescents. Whenthe door is closed and comes in Contact with the metal seal, the draftsealing is dependent on the resilience of the metal tube or the shape ofthe seal. Since such seals may serve well in forming a close contact ofthe door with the seal and the door casing when they are rst installed,metal will soon become fatigued and will lose its resilience and thereceases to be an intimately close contact of the door with the seal.

There are also other types of seals which do rely on rubber or the likematerials for forming the contact but these seals need to be cemented orsome such means need to be resorted in securing the seal to the moldingand the door casing. There are also other and serious objectionablefeatures due mainly to the structural design of such seals.

It is therefore an object of the present invention to provide a doorseal. It is still a further object to provide a door seal adapted forproviding silencing. It is a further object of the present invention toprovide a door seal fabricated of rubber or the like resilient material.A still further object of this invention is the provision of a holderfor securing the resilient material. A further object is the provisionof the holder which aifords ease in securing the said resilientlmaterial with the door casing. A still further object of the presentinvention resides in the provision of a means for securing the resilientmember of the seal without the need of cementing. A further object isthe provision of a door seal having means for securing the resilientmember to a door casing by means of locking the same with the molding ofthe seal.

I have now discovered and invented a door seal comprising an elongatedresilient member, the said resilient member having a body and a base,the said body and base being integral with each other, the said bodybeing hollow, a molding, the said molding having one at portion toconform with and be secured to a door casing, and a base portion toconform and secure the said resilient member, and means for securing thesaid molding to a flat surface, and I am now able to avoid thedisadvantages of the prior art and am able readily to accomplish theobjects set forth.

While some of the more outstanding features, and advantages of thisinvention have been hereinbefore indicated, others will become apparentfrom the following disclosures, taken in conjunction with theaccompanying drawing, in which:

Fig. 1 is a front view of a conventional door as seen when viewed fromthe outside. The heavy lines represent the seal of my invention.

Fig. 2 is a partial view of the door casing.

Fig. 3 is a sectional view taken along the line 3--3 of the Fig. 2,showing the sealer or molding made of metal, and showing the resilientmaterial encased therein.

Fig. 4 is a sectional view showing the resilient material, and themolding made of wood, with the rcsilient material locked in place.

Fig. 5 is a sectional viewv showing a modification of my inventionhaving a wood molding. y y

Fig. 6 is a sectional view showing a modication of my invention having ametal molding.

The resilient member 10, shown in the Figs. 2, A3, 4, and 6, and theresilient member 16 which is shown in the Fig. 5 is preferably made ofrubber, and for best results I prefer that it is made of rubber ofnumber-40 durometer. It will be noted that the members 10 shown in thevarious figures are identical with each other. The moldings used tosecure the members 10 vary in structure. The resilient member 16 whichis shown in Fig. 5 is a modication of the resilient members shown in theother figures. It will be noted that the molding 17 is fabricated toconform to the shape of the base 20 of the resilient member.

The resilient member comprises of an elongated body 10, and the base 19.In the instance of the modified form of my invention shown in the Fig.5, the resilient member comprises the elongated body 16, and the base20. It is obvious that the elongated body 16, and the base 2t) areintegral with each other. It is likewise obvious that the elongated body10, and the base 19 of the other members shown in the Figs. 3, 4, and 6are integral with each other. Thus a smooth transition surface isprovided between the body 16 and base 19 on one side of the elongatebody 10 and accomplishes tangential connection with the substantiallyhemispheric portion of the body 10.

I want particularly to point out that the elongated body of theresilient members 1l) and 16 are rounded laterally at the top surface topermit the corner of the door to be cleared when the door is beingclosed. This will be seen in the right-hand drawing of the Fig. 3. Itwill be noted, however, that when the door is finally closed that aportion of the rounded body of the resilient member extends toward thedoor, and that this portion is compressed by the door to form a tightseal with the door and the door seal of my invention.

To add to the resiliency of the resilient members 10 and 16, theelongated head is formed hollow lineally throughout the entire head andis of substantially hemispheric shape in cross section as indicated, forexample, in Figure 4.

The metal molding 13 is made of a strip of sheet metal folded back uponitself, and with the two edges of the metal further folded back andbeing substantially rounded.

The metal molding 18 shown in the Fig. 6 is made of a single strip ofsheet metal rounded at each of its ends to prevent damage to the doorframe and to the resilient member.

Referring particularly to the form of my invention as shown in Figs. 3,4, and 6, it will be noted that the resilient member 10 is secured tothe door casing 11 by means of being locked frictionally between thedoor casing and by the lip portion of the base locking matingly with themolding. The manner of locking of the device shown in the Fig. 5 issubstantially the same as in the other iigures mentioned above, but thebase of the resilient member extends further away from the base proper,and is L-shaped-like.

In actual use of the seal of my invention the resilient member 10, andin the case of the modified form, the resilient member 16, is placedcontiguously with the molding, the two members are then placed againstthe door casing by means of nails or screws holding the molding. It willbe noted that resort need not be made to cement or other securing meansother than that described above. The resilient member is locked in placeby its base, the molding, and the door casing.

When the moldingis secured in place to the door casing the resilientmembers 10, and 16, are securely held in place due to the structuraldesign of the resilient members and the molding conforming one with theother.

The Fig. 3 shows the same invention except that the molding 13 is madeof metal instead of wood, and the said molding is secured to the casing11 by means of the screw 12.

The Fig. 6 shows another modified form of my invention having the sameresilient member 10 as is shown in the Figs. 3 and 4, and the molding 18is slightly different in design. It will be noted that the middleportion of the molding is bent down to contact the door casing.

The Fig. 1 shows a conventional door 14, and shows the resilient member10, and the door casing 11.

I wish to point out particularly that the device of my invention is usedas a sealer to prevent the passage of drafts, dust, smoke and odors, butit also serves as a silencer. Since the rubber members are resilient,the shock of the door hitting against it is broken, and there is lesswear on the door and the casing due to the impact of the door.

I wish further to point out that my invention is not limited in its usein conjunction with outside doors, since I find it extremelyadvantageous for use for inside doors. For example, I nd my inventionvery useful in conjunction with inside hospital doors. And I nd it togreat advantage to use my invention in connection with windows.

Having clearly set forth the construction, utility and advantages of myinvention I wish particularly to state that it will be apparent thatchanges in the details of the construction and arrangement of thevarious members of the invention may be resorted to without departingfrom the spirit and scope of the invention as hereinafter claimed.

I claim:

A weather seal for door trim held against a fiat frame surfaceincluding: an elongate member of resilient material having in crosssection throughout its length a body consisting of a hollow portion ofsubstantially hemispheric configuration being connected integrally atits points of juncture to a solid tongue portion on one side with thesaid hemispheric portion, said connection describing a smooth transitionsurface and being grooved on the other side where said tongue joins saidbody; and a molding having a lip longitudinally along one edge mating inthe said groove between said base portion and said tongue to grip saidtongue in longitudinal position against said at surface; and securingmeans through said molding attaching said molding to said llat framesurface.
